Something I have noticed about openstudio and its geometry is that it is quite fussy. Here are my tips for drawing in openstudio.
- Be careful to name your thermal zones different names.
- Plan your drawing of the whole building before starting and make sure not to have too many surfaces
- Save versions frequently, close sketchup and reopen your model frequently
- If you see a white surface abort immediately and go back to a previous version
- Match your surfaces floor by floor, this means that you can correct your geometry as you go and saves a lot of pain at the end.
6.We frequently find missing surfaces when we move from OpenStudio to Legacy, so I don't think you are supposed to do that.
It doesn't directly answer your question, but I thought some tips could help
